Overview of BlackDiamond 12800 Series Power

Supplies

The BlackDiamond 12800 series switches can be powered by either AC or DC power supplies (PSUs). Power supplies in the BlackDiamond 12800 series switches are fully fault tolerant and load-sharing in an N+1 configuration. After the system is properly configured, if one PSU fails, the others will provide sufficient power to operate a fully loaded switch.

The BlackDiamond power supply units are intended for use in specific BlackDiamond switches only. Table 9 lists the power supplies for use in the BlackDiamond 12800 series switches.
